KTuner Reflash for 2005-2006 Acura RSX Type-S. An amazing alternative to Hondata Kpro, or KTuner end-user is the KTuner reflash for your stock ECU. This KTuner reflash is for your factory 05-06 RSX ECU and requires no wiring changes or replacement ECU's. We simply reflash your ECU and return it to you to plug back in. ** Will require shipping your ECU to us for the reflash ** The KTuner reflash will provide a broad, usable powerband from your K20 engine with plenty of top-end power to put a smile on your face.

Choosing a reflash not intended for your modifications will yield poor results and possible loss in power and driveability. If your engine setup doesn't exactly match the modifications listed for the reflash, we HIGHLY recommend going with the KTuner End-User system instead of a reflash. The KTuner End-user will allow you to upload/flash your ECU yourself with a KTuner reflash file, switch between reflash files as desired, make any other setting changes desired, or tune the system, etc. With the KTuner reflash service you cannot make any changes yourself, and would need to purchase another reflash if you find you need to switch to a different reflash file.

5. Your ECU will be shipped back to you within 1-2 business days. We will email shipping notification and tracking information at this time so that you can know when to expect your ECU.
6. When you receive your ECU back from the reflash, simply plug into your vehicle and enjoy!


Ask a Question
  • Hello, I was wondering if the Reflash #2 will cause any problems with getting the car inspected. As in would it still allow inspection monitors for the o2 sensor? I live in NC and I believe the county I'm in does not require an emissions test, but just wondering. Thanks.

    Since this disables the secondary 02 sensor, the emissions/catalytic monitor will not function. This will not give a check engine light, but if a code reader is connected and the ECU scanned it will show that it hasn't ran the monitor/tests. This is not intended to be street or emissions legal.

  • Do you have this option for 2006 rsx base?

    Sure do: KTuner 2005-2006 Acura RSX Base Model Reflash

  • Hello does the 05-06 reflash also disable the immobilizer??

    The immobilizer can be disabled during the reflash if desired.  If you'd like it disabled, simply write this request in the comments box when placing your order.

  • What would be the best option if I were to do Reflash #2 and still want to pass smog checks? I was told to purchase a separate ECU and send that it but then there’s the immobilizer issue. Does the Reflash disable the immobolizer?

    We can disable the immobilizer when doing the reflash if desired.  That way you can use two different ECU's as desired.  Simply write the request to also disable the immobilizer in the comments box at checkout.  Thanks,
